Detailed Description

Base abstract class for Windows 32 displays. Implements the window creation in a separate thread and the associated event handling functions for Windows 32 displays. Uses calls to a renderer to do some display. (i.e. all display methods are implemented in the renderer)

Member Enumeration Documentation

◆ vpScaleType

enum vpDisplay::vpScaleType
inherited

Values that could be applied to a display to down scale the size of the display.

Enumerator
SCALE_AUTO 

Auto down scaling factor computed fom the screen resolution.

SCALE_1 

Display and image have the same size.

SCALE_2 

Display width and height is down scaled by 2 wrt the image size.

SCALE_3 

Display width and height is down scaled by 3 wrt the image size.

SCALE_4 

Display width and height is down scaled by 4 wrt the image size.

SCALE_5 

Display width and height is down scaled by 5 wrt the image size.

SCALE_6 

Display width and height is down scaled by 6 wrt the image size.

SCALE_7 

Display width and height is down scaled by 7 wrt the image size.

SCALE_8 

Display width and height is down scaled by 8 wrt the image size.

SCALE_9 

Display width and height is down scaled by 9 wrt the image size.

SCALE_10 

Display width and height is down scaled by 10 wrt the image size.

SCALE_DEFAULT 

Display and image have the same size. Similar to vpDisplay::SCALE_1.

bool  use_centered_moments,
const vpColor &  color,

)
staticinherited

Display an ellipse from its parameters expressed in pixels.

Parameters
I: Image to consider.
center: Center $(u_c, v_c)$ of the ellipse.
coef1,coef2,coef3: Depending on the parameter use_centered_moments these parameters are:
  • the centered moments expressed in pixels: $\mu_{20}, \mu_{11}, \mu_{02}$;
  • the major and minor axis lenght in pixels and the excentricity of the ellipse in radians: $a, b, e$.
use_centered_moments: When false, the parameters coef1, coef2, coef3 are the parameters $a, b, e$. When true, the parameters coef1, coef2, coef3 are rather the centered moments $\mu_{20}, \mu_{11}, \mu_{02}$ expressed in pixels. In that case, we compute the parameters a, b and e from the centered moments.
color: Ellipse color.
thickness: Ellipse thickness.

All the points $(u_\theta,v_\theta)$ on the ellipse are drawn thanks to its parametric representation:

\[ \left(\begin{array}{c} u_\theta \\ v_\theta \end{array} \right) = \left(\begin{array}{c} u_c \\ v_c \end{array} \right) + \left(\begin{array}{cc} \cos(e) & -\sin(e) \\ \sin(e) & \cos(e) \end{array} \right) \left(\begin{array}{c} a \cos(\theta) \\ b \sin(\theta) \end{array} \right) \]

with $0 \leq \theta \leq 2\pi$.

The following example shows how to use for example this function to display the result of a tracking.

vpMeEllipse ellipse;

vpDisplay::display(I);
ellipse.track(I);
vpDisplay::displayEllipse(I, ellipse.getCenter(), ellipse.get_mu20(),
